I have a custom column for the information. Until now I added it manually.
Here are a few examples from different collections:
http://archiveofourown.org/works/585034
http://archiveofourown.org/works/512589
http://archiveofourown.org/works/488775/chapters/852745
If I could configure it on the custom columns tab, that would be good.
I think the stories that are in collections have two different urls.
This is on the authors page
http://archiveofourown.org/works/505088
And this is on the page of the collection
http://archiveofourown.org/collectio...2/works/505088
